The effects of the thermo-mechanical parameters, in a Hot Strip Mill equipped with a coilbox, on the mechanical and micro-structural behavior of a titanium stabilized interstitial free steel are reported. The coiling temperature has the most significant effect on the mechanical properties. Increasing the coiling temperature reduces yield stress, tensile strength and hardness while it increases the elongation at fracture and drawability. The mechanical properties have been interpreted, through metallographic studies, in terms of ferrite grain size and of occurrence, distribution and size of the titanium precipitates.
